If you are comfortable learning that way and you think it will help it stay in the memory then go for it. I did a 3 day supercourse back when CSM were still going. Best three days biking I ever did and it did stay in the memory. It made me approach the test as just another lesson and if i screw up well dont repeat it!.....I passed first time.
Now if only the same could be said for my car...Class 2 and class 1 artic.......
Which ever way you do it it really will be the best thing you ever do and I wish you luck with it
